Letters Patent lV'o. 78,09L dateal May '19, 1868.

IMPROVEMENT IN'GHURNS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, AUSTIN D. HOFFMA I -I, of the city of Minneapolis, in the county of Henne nin, anei State of Minnesota, have invented a, new and useful Improvement in Ghurns; and I do hereby declare that the following is a full, clear, and exact descriptionof the same, reference being had to the annexed drawings, in which Figure 1 is a perspectiveyiew, and

Figure 2 is an elevation.

The same letters are employed in both the figures for the indicationof the same parts.-

.A is the top of the churn, to which is attached-the verticalstandard 13, having an elbow at the top, through which isaL hole, serving as an upper guide for the dasher C,which passes through the cover into the body of the churn. The dasher is operated By a. winch, D, turning in hearings on the erm B and the body of thestamierd B. The crank, D, is attachedto the pitman E, which 'is'attached adjustably to the dasher by collars F F.

On the lower end of the pitman, which oscillates with the action ofthecrank, is a segment, E, having cog s on its face next the dashe r. These cogs mesh into the pinion G, which is keyed to the shaft, so that, as the pitmen rises and falls, it shall give a. vertical reciprocating motion to the dasher, and, also, by the oscillaition' of the seg-n'lent E, give a reciprocating. rotary motion. v

'The-(lasher-blades, H and I, I prefer to construct as shown, but they t ey be'varied.

What Iclaiui'as my invention, and desire to secure by Letters Patent, is-

The combimition of the winch and crank, the pitlnan E, segment E, and pinion G, for communicating both a. vertical and rotary reciprocating action to the dasher, substantially as set forth.

In testimonyrwhereof, I have signed my'nam e to this specificution in the presenceof two subscribing witnesses.

AUSTIN D. HOFFMAN.
